Brief description of the drawings
Fig. 1 is a kind of explosion-proof mixing reactive power compensation cabinet structural representation of the utility model.
Embodiment
Specific embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings.As shown in Figure 1：It is a kind of explosion-proof
Reactive power compensation cabinet, including cabinet are mixed, middle part top is provided with controller 1 in the cabinet, and the left side of controller 1 is provided with
Multiple current transformers 2, right side are provided with message exchange 3, and the lower left corner of controller 1 is provided with multiple breakers 4, the control
The lower section of device 1 is provided with contactor group, and the line that is respectively arranged below with of the contactor group mends capacitor 5 and mutually mends capacitor 6.
The contactor group mends capacitor 5 by multiple compositions with line.
The contactor group is mended contactor 7 by line and formed with mutually mending contactor 8
The line mends capacitor 5 and is mutually equipped with temperature sensor 9 in benefit capacitor 6.
The current transformer 2 electrically connects with the binding post on controller 1 respectively, the controller 1 and information exchange
The wireless connection of device 3, the line are mended contactor 7 and electrically connected with mutually mending contactor 8 by compensating controlling bus with controller 1, institute
State the temperature sensor 9 that line is mended capacitor 5 and mutually mended in capacitor 6 to electrically connect with controller 1 by temperature transfer bus, institute
State breaker 4 to electrically connect with line benefit contactor 7 by fuse, the line mends contactor 7 and mends electricity with line respectively by inductor
Container 5, mutually benefit capacitor 6 electrically connects.
When the utility model uses:Breaker 4 is connected during work first, now controller 1 enters working condition, control
